This isn't all that unheard of, I personally know someone who was put in a similar situation when they were an undocumented child. She was taken to the emergency room for her stab wounds and she luckily lived in a sanctuary city so her parents did not fear going to the police. The person who did that to her was brought to justice however not before he had time to rape another child.

But not every woman or child lives in a sanctuary city and even with the U-visa designed to help the victims of such crime it is left toothless because often local law enforcement refuses to cooperate with the issuing of U-visas.
